SIGPAUSE(3) | Library Functions Manual | SIGPAUSE(3)

# NAME

sigpause — atomically release blocked signals and wait for interrupt

# LIBRARY

Standard C Library (libc, -lc)

# SYNOPSIS

#include <signal.h>

int
sigpause(int sigmask);

# DESCRIPTION

This interface is made obsolete by sigsuspend(2).

sigpause() assigns sigmask to the set of masked signals and then waits for a signal to arrive; on return the set of masked signals is restored. sigmask is usually 0 to indicate that no signals are to be blocked. sigpause() always terminates by being interrupted, returning -1 with errno set to EINTR.

# SEE ALSO

kill(2), sigaction(2), sigprocmask(2), sigsuspend(2), sigblock(3), sigvec(3)

# HISTORY

The sigpause() function call appeared in 4.2BSD and has been deprecated.
